` SPECIFICATION forming part of Letters Patent No. 760,828, dated May24, 1904.

Application led October 17, 1903.

To all whom, t may concern:

Be it known that we, JOHN S. WECKMAN and ROBERT J. M1LLARDcitizen`s of`the United States, residing at Carnegie, in `the county ofv Alleghenyand State of Pennsylvania, vhave invented certain new and usefulImprovements in Trolleys; and we do hereby declare that the following isafull, clear, and exact description of the samereference being had tothe annexed drawings, making a part of this specilication, and to thefigures of reference marked thereon, in which- Figure 1 is a viewshowing a portion of a trolley-wire, showing the trolley-wheel aroundthe pole and the trolley-wheel detached from the wire. Fig. 2 is a viewshowing a portion of a car, the pole properly attached, and the wire incontact with the trolley-pole. Fig. 3 is a detached View of the lowertrolley-pole spring. Fig. 4 is a bottom or under yside view of thetrolley-pole head and its different parts.

The present invention has relation to trolleys; and it consists in thedifferent parts and combination of parts hereinafter described, andparticularly pointed out in the claim.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings. v

In the accompanying drawings, 1 represents the pole, which may be ofusual construction and of a length suiiicient to properly engage thewheel 2 with the trolley-wire 3. To the top or upper portion of thelpole is, attached the head 4, to which head are pivotally attached thearms 5, which arms will extend beyond the head,` and the portionsextending beyond the periphery of the wheel 2 diverge from each other,as illustrated in Fig. 4. For the purpose of preventing any accidentalmovement of the arms 5 they are located upon the inner faces of thehead, and the different parts by which the arms and wheel are actuatedare within the width of the head.

equivalent, to which cross -jbar is connected Serial No. 177,407. (Nomodel.)

` the link 9 and the link connected at its lower or opposite end to thehinge 10, which hinge is connected to the free end of the spring 11,which spring is connected to the head 4 by means of a suitableclamping-bolt 12.

The spring 11 is so constructed that it will have a tendency to pull thelink, which in turn pulls the lower ends of the arms 5 and will comeabove the trolley-wire 3.

ssl

The position o f the arms 5 (shown in Fig. 1)

is their normal one when the wheel 2 is disconnected from thetrolley-wire 3; but when the trolley-wheel 2 is brought in contact withthe trolley-wire 3 the wheel 2 will be moved downward. with reference tothe head 4, which turns the upper ends of the arms 5 downward and thelower or inner ends of said arms upward, the spring 11 being of such atension that the pressure of the wheel 2 upon the wire 3 will overcomethe spring and pull its free end toward the head 4, as illustrated inFig.

.2, thereby bringing the upper ends of the -erably of the form shown andis v attached to the turn-table 15, lwhich turn-table may be of the formshown, or it may be of vany other desired form, inasmuch as theturn-table within itself forms no particular part of the presentinvention.

To the free end of the spring 14 is journaled the roller 16, whichroller comes under the pole 1, as illustrated in Fig. 2, and the'tensionof the spring 14 is such that it will hold the roller 16 in closecontact with the pole 1 and have a tendency to lift the pole so as toelevate its free end and bring the wheel 2 in proper contact with thewire 3.

It will be understood that the instant the wheel 2 leaves or starts toleave the trolleywire 3, or, in other Words, jumps the trolleytheirupper ends, so as to bring them above the trolley-wire and prevent thewheel E2 from leaving the wire 3.

We have not shown in the drawings the ordinary rope attached to thetrolley-pole or its head; but it will be understood that this may beattached in any convenient and well-known g manner.

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is

The combination of a pole, a head iXed thereto, the members of the headprovided with slots, arms pivoted to the head, an axle and atrolley-wheel mounted thereon, said aXle extended through the slots inthe head, a spring secured to the head, a hinge connected to the freeend of' the spring, a cross-bar eonneeted to the lower ends of the arms,and a link connected to the cross-bar and spring, 2O substantially asand for the purpose speeiiied.

In testimonyT that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.
